Developers have confirmed it is their intention to build a housing development on community football fields.
NPL Estates have met with residents in Thornton, who questioned them on the work being carried out on Bourne Way playing fields.
But the proposed development has already been met with opposition from councillors who say they want the green space to be protected.
The area on the corner of Bourne Way and Fleetwood Road North is currently designated as a recreational open space by Wyre Council.
Coun Penny Martin, ward councillor for Cleveleys Park, said: “The meeting was just to get to the bottom of what their intentions actually are.
“I’m satisfied they’ve given us answers but obviously they’re not answers we want.”
Ian Honeybill, from NPL Estates, said: “We are considering proposals and yes it might end up as a housing application, for probably up to 100 homes. There will be a full public consultation done.”
Residents first became aware of the possible changes to use of the field when football teams playing there were asked to find new accommodation for the coming season.
The developers have announced they will offset the potential loss of the pitches with the creation of a community sports complex at Poolfoot Farm, working with Fleetwood Town FC.
But Coun Martin added: “If they’re offsetting the loss of football pitches on Bourne Way there you’re still losing green land.”
